Revise IDE folders locking mechanism (don't fail startup if all ports in range are taken, limited network due to firewall/VPN)

PROBLEM 1
If all the 50 ports between 6942 and 6991 are reserved, taken by the other apps or firewall doesn't allow IDE to bind on them, startup fails with the below exception:

WORKAROUND: run the following commands in the Administrator console (cmd.exe):

netsh int ipv4 set dynamicport tcp start=49152 num=16383
netsh int ipv4 set dynamicport udp start=49152 num=16383

C/C++ detected

If the above doesn't help, please try these commands instead:

net stop winnat
net start winnat

PROBLEM 2
Unable to start the IDE with a network limited due to firewall/VPN: See IDEA-253939 for example.

WORKAROUND
Add -Djava.net.preferIPv4Stack=true to the IDE's .vmoptions file and start the IDE.
Check here to find the .vmoptions file: https://intellij-support.jetbrains.com/hc/en-us/articles/206544869 .

@Sofia.Byzova To lock folders IDE is starting a server on localhost, it tries to bind on the first available port between 6942 and 6991, this exception is thrown if IDE was not able to bind on any of the ports in this range. All 50 ports are unlikely to be already used on a machine, so it appears to be a networking issue or some security software which doesn't permit IDE to bind on any port in this range even on localhost interface.

You can check with TcpView if these ports are already taken: https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview . It will show the process using the ports.

But in case of the firewall it can just block the bind operation and TcpView will not show anything.

netsh winsock reset followed by the reboot usually helps.

We have a lot of similar reports, some of them are related to Hyper-V reserving the huge range of ports: https://intellij-support.jetbrains.com/hc/en-us/articles/360007568559?page=1#comment_360001282960 .

Suggested solutions:

increase the default range (current one is from 6942 to 6991)
add another range with higher port numbers if the default range fails
fall back to platform specific locking (Mutex on Windows, Sockets on Unix)
on Windows ensure that the port we want to use is not in the list of excluded ranges netsh interface ipv4 show excludedportrange protocol=tcp. We can do it only if default range fails to not waste time on checking in other cases.
any other suggestions?

After installing this update, applications may not be able to reserve or bind to ports that previously worked.
To resolve this issue, use the following workaround.
Check if the port you want to bind to or reserve is already reserved on the container host. For example, you can use netsh as follows:
netsh interface ipv4 show excludedportrange protocol=tcp
If the port is not reserved, you may use it. If it is reserved, choose a different port.

Would it be problematic to just bind to a different address in the 127.0.0.0/8 loopback range?
Line 87 of BuiltInServer.kt calls InetAddress.getLoopbackAddress() which always returns IPv4 127.0.0.1 or the IPv6 ::1.
Could it not just be set to always use some other address consistently like 127.88.88.88 where it's unlikely any other program would be bound to those 50 ports on that exact address?

it won't help when these ports are reserved by the OS and reported in netsh interface ipv4 show excludedportrange protocol=tcp output. As you can see, it's not interface specific.

So I've just got it again. TcpView shows that those ports are free.

I've opened the firewall and see the following picture:

I haven't set anything up specially but I see some connections of IDEA are blocked. Why?.. Even after manually unlocking them, the issue still persists...

Yes, reserved by the OS. See the WORKAROUND section in the issue description.

The same issue happens on Linux if loopback interface is misconfigured (in my case 127.0.0.1 was not assigned to loopback for some reason). Restarting lo interface solved the issue for me (sudo ifconfig lo down, sudo ifconfig lo up)

Hi JetBrains developers. Do you use those TCP connections through the loopback/localhost (127.0.0.1) for the inter process communication (IPC) between the locally running IntelliJ modules? There are several bug reports like this and all of them seem to be triggered by conflicts with firewalls or VPNs widely used these days. Did you consider some other IPC implementation that doesn't depend and doesn't conflict with any firewall or VPN? For example:

UNIX domain socket
Named pipe
Shared memory file

The UNIX domain socket is natively supported even in Windows, from Windows 10 Version 1803.
https://bsmadhu.wordpress.com/2018/08/22/unix-domain-socket-support-in-windows/
https://unwcf.com/posts/unix-sockets/
There is an ongoing and partially done development of supporting UNIX domain socket in Java. It's called JEP-380
https://openjdk.java.net/jeps/380
https://bugs.openjdk.java.net/browse/JDK-8238588

Java can read named pipe but can't create it without using JNI or JNA:
https://cdimascio.wordpress.com/2014/01/11/named-pipes-with-java/

For shared memory file you can write your own library based on the java.nio.MappedByteBuffer class or use a library like Mappedbus:

FYI I was running into the same issue. netsh winsock reset as well as shutting down any HyperV VM followed by a reboot solved the issue for me.

Hi,

I'm looking to change over to Rider from VS but I can't get it to open at all.
Crashes on startup with the exception above.

I've tried all the workarounds suggested but nothing works.

It's a fresh install of Rider 2020.2.

Not running Hyper-V.
Attached the output of "netsh interface ipv4 show excludedportrange protocol=tcp"

I've been looking to change to Rider for about a year now but every time I install a new version I get this error.

Any help would be appreciated.

Thanks,
Quentin.

you have the required range reserved by the system: 6905 - 7004 according to the provided screenshot. Not sure which app/service is adding this range to the excluded ports, but this command when you run it from Administrator is supposed to reset the excluded ports: netsh int ipv4 set dynamicport tcp start=49152 num=16383.

I did try running both those netsh commands but it didn't make any difference.
Do I need to do anything else after run them and before I start Rider?

For some reason these commands do not remove 6905 - 7004 excluded range for you. No ideas why it doesn't work on this specific system, sorry.

I'm also seeing this issue and unfortunately the work around is not allowing me to start either IntelliJ or PyCharm.

Since the IDE will bind to port 6942 to 6991, this solution that reserves ports before Hyper-V works for me: https://stackoverflow.com/a/54727281/3689736

The same happened for me, the workaround is still working. I am using WSL2 a lot. A lot of ports below 10000 were affected by this (like a third) for me including huge 7800-8300 range which stopped a lot of apps from working, not only IDEA-like ones.

please contact support at https://intellij-support.jetbrains.com/hc/requests/new with the logs folder attached (https://intellij-support.jetbrains.com/hc/en-us/articles/207241085). See if reinstalling PyCharm from https://www.jetbrains.com/pycharm/download/index.html helps. Your problem doesn't seem to be related to this specific ticket.

I hit this with Rider and found that adding -Djava.net.preferIPv4Stack=true to the VM options allows it to start properly with VPN enabled.

Workaround sometimes works for me, sometimes doesn't; granted I do use a likely troublesome combo:

Corporate VPN
WSL2
Hyper-V
Corporate-managed security solution (firewall is almost impossible to configure unless you have extensive paperwork)

In the end, binding to a port for file / resource locking is not recommended, the solution is to use platform-specific mechanisms.

The most terrible thing PHPStrom (2021.2.1) doesn't show any message just a splash screen with a dead progress bar. I spent half of hour to find why…

I just hit this as well and the lack of alert dialog in 2021.2.1 seems like a regression. I had to go back to 2021.1.3 to realise what was wrong.

The
net stop winnat
net start winnat
solution fixed this for me.

I had never had this problem until today, even thought I have Hyper-V active. I wonder if this issue has got worse since this weeks updates from Microsoft, which I applied yesterday. I have a X-Server program, X410, which fails to start with similar symptoms and it was also fixed by stop/starting winnat.

This issue also happens during installation of tools not just starting. When the tools attempt to "update plugins" after their installation they fail to finish.

That this is not fixed after almost two years is bad, that the IDE gives zero indication that there's a critical problem is far worse. Do you understand how to do basic exception handling, JetBrains?

I guess it doesn't matter since there is zero chance of me buying Rider after such a poor first-use experience. After using Visual Studio exclusively since .NET Framework 1.0, I was thinking it would be impossible for any would-be competitor to be worse - but you've not only proved me wrong, you've failed at the very first step - so congratulations on being terrible!

Understandably you're frustrated for not being able to use Rider. However, basing your conclusions entirely on this initial bad experience, I'm afraid you've misjudged Jetbrains. Their products are really great. Not perfect, no, but when working for some time with their IDEs you will see that they really care about developer experience, and they have improved my daily life like no other software. I wish more companies would take example from Jetbrains.

The above issue has also affected me, hence I'm following it. However, I applied the workaround which worked, and was able to continue my work.

Rider may actually be a good alternative to VS for you, once you get it running, so it would be a lost opportunity for yourself to burn it so quickly.
Do reconsider, and if you have any issues applying the workaround please write again, but without the snarks. I'm sure someone will be able to help.

If you're looking to analyze the log file then these commands may help:

Maybe just like the one-click virusscanner directory exclusion, JetBrains could add a button that does `netsh int ipv4 add excludedportrange protocol=tcp startport=<portnr> numberofports=1` on the ports it requires. If it's a range it needs, you can increase the `numberofports=`.

People! If you are a Unity developer using Rider on Windows 10. DONT SET YOUR PORT TO start=49152 num=16383. It will break your unity debugger. Set the range to "start=32768 num=32767" instead. This costs me 6 hours to figure out.

https://docs.microsoft.com/en-US/troubleshoot/windows-server/networking/default-dynamic-port-range-tcpip-chang

To comply with Internet Assigned Numbers Authority (IANA) recommendations, Microsoft has increased the dynamic client port range for outgoing connections in Windows Vista and Windows Server 2008. The new default start port is 49152, and the new default end port is 65535. This is a change from the configuration of earlier versions of Windows that used a default port range of 1025 through 5000.

The suggested command resets the dynamic client ports range to the IANA recommendations.

Hello to everyone in this "chat", lemme join the waiting list.

So... it's been 2.5 years since this bug was open? I guess we'll need to wait another 7 or so years until it resolved if ever (as per experience with infamous rsync bug). The fact that they have a link to blog post with startup errors embedded in a stack trace in error window suggest that there is no hope for seeing it solved in a near future (if ever, since link is already there).

Oh, right. jetbrains, I have an amazing idea for you. Check stack trace for specific errors (as per blog post) and just display workaround in the same window with bold font. Then you will be able to resolve this and other startup issues. Easy-peasy.
